NXP Semiconductors MCIMX283DJM4A

Overview

MCIMX283DJM4A from NXP Semiconductors is an ARM926EJ-S-based applications processor operating at up to 454 MHz, featuring 128 KB on-chip SRAM, dual CAN interfaces, single 10/100 Ethernet MAC, and integrated PMU with Li-ion battery charging. It targets industrial HMI panels, portable medical devices, and smart energy meters requiring low-power, high-integration embedded control.

For engineers reviewing the MCIMX283DJM4A datasheet, MCIMX283DJM4A pinout, MCIMX283DJM4A application, or MCIMX283DJM4A equivalent, key selection considerations include its –20°C to +70°C temperature grade, MAPBGA-289 package, LCD interface support, and absence of L2 switch or dual Ethernet-distinguishing it from i.MX286/i.MX287 variants.

Technical Context

The MCIMX283DJM4A implements the ARM926EJ-S core with 16 KB instruction and 32 KB data caches, ETM9 debug support, and parallel JTAG interface. Its clock architecture uses a 24 MHz crystal input for PLL generation and a separate 32.768 kHz RTC crystal, enabling precise timekeeping during deep-sleep states.

Power management integrates a triple-output DC-DC switching converter, linear regulators, battery charge control, and brownout detection across VDDD, VDDA, VDDIO, and VDD4P2 rails. Memory subsystem supports mobile DDR, DDR2, and LV-DDR2 up to 205 MHz, plus NAND Flash with 20-bit BCH ECC across up to eight devices.

FAQ

What is the maximum operating frequency of the MCIMX283DJM4A CPU core?

The MCIMX283DJM4A features an ARM926EJ-S core rated for operation up to 454 MHz. This frequency is achievable under specified voltage (VDDD ≥ 1.35 V) and thermal conditions (junction temperature ≤ 85°C), as confirmed in the IMX28CEC datasheet Section 3.1.2. The MCIMX283DJM4A maintains this performance while supporting dynamic voltage scaling through its integrated PMU.

Does the MCIMX283DJM4A support secure boot, and what cryptographic functions are hardware-accelerated?

Yes, the MCIMX283DJM4A supports secure boot via High Assurance Boot (HAB4) and includes hardware-accelerated 128-bit AES decryption, SHA-1, and SHA256 hashing. These functions are implemented in the DCP (Data Co-Processor) and OCOTP modules, enabling authenticated firmware loading and runtime integrity verification without software-only overhead.

What display interfaces does the MCIMX283DJM4A support, and what is the maximum color depth?

The MCIMX283DJM4A integrates an LCD Interface (LCDIF) supporting 24-bit RGB DOTCLK modes, enabling direct connection to WVGA and higher-resolution color TFT panels. It does not support LVDS or MIPI DSI; the 24-bit interface provides full 16.7M-color capability with programmable timing and polarity control per the i.MX28 reference manual.

Can the MCIMX283DJM4A operate from a single Li-ion battery without external power regulation?

Yes-the MCIMX283DJM4A integrates a complete PMU with a triple-output DC-DC converter and linear regulators, allowing direct operation from a 3.1–4.242 V Li-ion battery. Its VDD4P2 rail generates a regulated 4.2 V supply, and the PMU handles battery charging, brownout detection, and seamless 5-V/battery source switching-eliminating need for external power ICs.

How many CAN interfaces does the MCIMX283DJM4A include, and what protocol version do they support?

The MCIMX283DJM4A includes two Controller Area Network (FlexCAN) interfaces compliant with CAN 2.0B protocol, supporting bit rates up to 1 Mbps. Both controllers implement full CAN message buffering, error handling, and loopback self-test modes, as documented in the i.MX28 Reference Manual Chapter 33 and verified in Table 2 of IMX28CEC Rev. 4.
